Report on the sessions of the Meteorological Association of the International Union of Geodesy and Geophysics held at Edinburgh, September 17–26, 1936

About 50 delegates, representing 15 countries, were in attendance. The contacts between delegates from the different countries were most stimulating and helpful, and a great deal of benefit- was derived thereby. The basic theme adopted for the Edinburgh Meeting was “The problem of atmospheric disturbances,” which quite naturally resolved itself into six different divisions, as follows: (a) The definition of a disturbance; (b) origin of disturbances; (c) structure of cyclones; (d) Interaction between different layers of the atmosphere; (e) radiation and its role in atmospheric disturbances; and (e) precipitation. A number of instructive papers were read under these six heads and, in addition, there were about a dozen papers of a miscellaneous nature. All were interesting and many evoked discussion.
